Zoe's new carpet

The other day a bought a carpet for Zoe... and how much does a carpet cost? I need help here because my husband Thomas said a carpet should cost no more than 10 EUR, and the thing is that I spent quite a lot more than that, and as I told Thomas, it's not just a carpet, it's the place where Zoe will spend lots of time playing, it makes her really happy, and it even has butterflies... so isn't it worth it?
